Command Modes
• CONFIG-ROUTER-BGP-ADDRESS-FAMILY
• CONFIG-ROUTER-BGP-VRF-ADDRESS-FAMILY
Usage Information This command is used to congure administrative distance for eBGP route, iBGP route, and local BGP route.
Administrative distance indicates the reliability of the route; the lower the administrative distance, the more reliable
the route is. Routes that are assigned an administrative distance of 255 are not installed in the routing table.
Routes from confederations are treated as iBGP routes.

IPv6
OS10# configure terminal
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# address-family ipv6 unicast
